Description

Technical Field

[0001] This application relates to the field of tensile testing instruments, and in particular to a tensile testing apparatus for thermoplastic composite optical cable reinforcing cores. Background Technology

[0002] Thermoplastic composite fiber optic cable reinforcing core is a material used to enhance the mechanical strength and tensile strength of fiber optic cables. It is usually composed of thermoplastic polymers and reinforcing materials (such as glass fiber, carbon fiber, etc.). This material has characteristics such as high strength, good flexibility, corrosion resistance, lightning strike resistance, and electromagnetic interference resistance. It is particularly suitable for protecting optical fibers from damage by external forces. Thermoplastic composite fiber optic cable reinforcing core is often tested using a tensile testing machine. When using a conventional tensile testing machine, after the machine body is powered on, a fixing frame is installed on the surface of the machine body. The fiber optic cable is installed on the surface of the machine body with the help of the fixing frame, and the machine body stretches the fiber optic cable to test the quality of the fiber optic cable.

[0003] Regarding the aforementioned technologies, the inventors believe that conventional tensile testing devices cannot effectively detect the breakage process and location of optical cables when they break with the naked eye. This makes it impossible to adjust and improve problematic areas in the optical cable manufacturing process, thus affecting the effectiveness of upgrading optical cable material processing.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0005] To address the problem that conventional tensile testing instruments have difficulty identifying the locations where optical cables are prone to breakage, this application provides a tensile testing device for the reinforcing core of thermoplastic composite optical cables.

[0006] The tensile testing device for the thermoplastic composite optical cable reinforcing core provided in this application adopts the following technical solution:

[0007] A tensile testing device for the reinforcing core of a thermoplastic composite optical cable includes a body and a slide rail. A fixing frame is fixedly installed on the surface of the body, and an adjusting frame is slidably connected to the surface of the slide rail. The dimensions of the slide rail surface are adapted to the dimensions of the inner wall of the adjusting frame. A control frame is rotatably installed at one end of the adjusting frame, and a monitor is rotatably connected to the inner wall of the control frame. One end of the slide rail is fixedly installed on the surface of the body, and the slide rail has a "T" shaped cross-section. The dimensions of the monitor surface are adapted to the dimensions of the inner wall of the control frame.

[0008] Preferably, the inner wall of the adjusting frame is threaded with a fixing bolt, one end of which is engaged with the surface of the slide rail, and the fixing bolt and the slide rail are perpendicularly distributed.

[0009] Preferably, the surface of the slide rail is provided with a plurality of limiting grooves, and the plurality of limiting grooves are evenly distributed on the surface of the slide rail.

[0010] Preferably, a baffle is slidably mounted on the top of the machine body, and an adjusting plate is slidably connected to the inner wall of the baffle. The dimensions of the adjusting plate are adapted to the dimensions of the inner wall of the baffle. Both the baffle and the adjusting plate are transparent plastic plates.

[0011] Preferably, both the shielding plate and the adjusting plate have slots on their inner walls, and a limiting block is engaged with the inner wall of the slot. One end of the limiting block is rotatably mounted to the inner wall of the adjusting plate, and a fixing spring is fixedly connected between the limiting block and the adjusting plate.

[0012] Preferably, a connecting frame is fixedly installed at the bottom end of the shield, and a slider is slidably connected to the inner wall of the connecting frame. The bottom end of the slider is fixedly installed to the top of the machine body.

[0013] Preferably, a limiting frame is rotatably connected to the inner wall of the connecting frame, a connecting spring is fixedly installed between the limiting frame and the connecting frame, and one end of the limiting frame is engaged with the top of the slider.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] 1. By mounting a slide rail on the machine body surface, an adjustment frame is slidably connected to the slide rail surface. A monitor is mounted on one end of the adjustment frame via a control frame, allowing the monitor to capture images of the position of the test material mounted on the fixed frame and transmit the images to a computer. This facilitates the staff's inspection of the broken location of the test material, enabling the equipment used for cable production to be debugged or repaired. A fixing bolt is threaded onto the inner wall of the adjustment frame, with one end of the fixing bolt engaging with the slide rail surface. This allows the adjustment frame to be easily moved to a suitable position using the slide rail and then fixed in place by the fixing bolt. Several limiting grooves are formed on the surface of the slide rail to increase the friction between the fixing bolt and the slide rail. Compared to existing technologies, this method effectively improves the tensile testing effect of optical cables.

[0016] 2. A shield can also be installed on the surface of the machine body. An adjusting plate is slidably connected to the inner wall of the shield, so as to shield the perimeter of the fixed frame with the shield and adjusting plate, avoiding injury to the monitor or surrounding personnel caused by the breakage of the detection material. The inner walls of both the shield and the adjusting plate are provided with slots, and the inner walls of the slots are engaged with limit blocks. A fixing spring is installed between the limit block and the adjusting plate, so as to push the limit block with the fixing spring and engage the limit block with the inner wall of the slot, making it easy to move the adjusting plate up and fix it with the limit block. A connecting frame is installed at the bottom of the shield, and the bottom of the connecting frame is slidably connected to the slider on the surface of the machine body, so as to facilitate the installation of the shield on the surface of the machine body with the connecting frame and the slider. A limit frame is rotatably connected to the inner wall of the connecting frame, and a connecting spring is installed between the limit frame and the connecting frame, so as to push the limit frame with the connecting spring and keep the limit frame engaged with the surface of the slider; effectively improving the use effect of the device.

[0022] The following is in conjunction with the appendix Figure 1 —4. This application will be described in further detail.

[0023] This application discloses a tensile testing device for a thermoplastic composite optical cable reinforcing core, referring to... Figure 1 - Figure 2The system includes a tensile testing machine body 1. During use, after the body 1 is powered on, a mounting bracket 2 is installed on its surface. The optical cable is then mounted on the body 1 using the mounting bracket 2. The body 1 stretches the optical cable to test its quality. A slide rail 3 is mounted on the body 1, and an adjustment bracket 4 is slidably connected to its surface. A monitor 6 is mounted on one end of the adjustment bracket 4 via a control bracket 5. The monitor 6 captures images of the position of the test material mounted on the mounting bracket 2 and transmits the images to a computer. This allows staff to easily check the location of any breakage in the test material, enabling adjustments or repairs to the cable production equipment and effectively improving the tensile testing results of the optical cable.

[0024] Reference Figure 2 The inner wall of the adjusting frame 4 is threaded with a fixing bolt 7. One end of the fixing bolt 7 is engaged with the surface of the slide rail 3. The slide rail 3 facilitates the adjustment frame 4 to move to a suitable position, so that the monitor 6 can take pictures of the detection material position at different heights. The fixing bolt 7 is used to fix the adjusting frame 4. Several limiting grooves 8 are opened on the surface of the slide rail 3. The limiting grooves 8 increase the friction between the fixing bolt 7 and the slide rail 3.

[0025] Reference Figure 3 - Figure 4 A shield 9 is installed on the surface of the machine body 1. An adjusting plate 10 is slidably connected to the inner wall of the shield 9. The shield 9 and the adjusting plate 10 shield the perimeter of the fixed frame 2, preventing the broken detection material from causing injury to the monitor 6 or surrounding personnel. Both the shield 9 and the adjusting plate 10 have slots 11 on their inner walls. A limit block 12 is engaged with the inner wall of the slot 11. The surface of the limit block 12 is rotatably connected to the inner wall of the adjusting plate 10. A fixing spring 13 is installed between the limit block 12 and the adjusting plate 10. The fixing spring 13 pushes the limit block 12, engaging it with the inner wall of the slot 11, facilitating the upward movement of the adjusting plate 10 using the limit block 12. The limiting block 12 is fixed and separated from the slot 11 to facilitate the retraction of the adjusting plate 10. A connecting frame 14 is installed at the bottom of the shield plate 9. The bottom of the connecting frame 14 is slidably connected to the slider 15 on the surface of the body 1. The connecting frame 14 and the slider 15 facilitate the installation of the shield plate 9 on the surface of the body 1. Separating the connecting frame 14 and the slider 15 facilitates the disassembly of the shield plate 9. A limiting frame 16 is rotatably connected to the inner wall of the connecting frame 14. A connecting spring 17 is installed between the limiting frame 16 and the connecting frame 14. The connecting spring 17 pushes the limiting frame 16 to keep the limiting frame 16 locked to the surface of the slider 15, effectively improving the stability of the shield plate 9.

[0026] The implementation principle of the tensile testing device for the thermoplastic composite optical cable reinforcing core in this application embodiment is as follows: A slide rail 3 is installed on the surface of the machine body 1. An adjustment frame 4 is slidably connected to the surface of the slide rail 3. A monitor 6 is installed at one end of the adjustment frame 4 via a control frame 5, so that the position of the test material installed on the fixed frame 2 can be photographed by the monitor 6 and the image can be transmitted to the computer. This allows the staff to check the location of the fracture of the test material, thereby debugging or repairing the equipment for producing cables. A fixing bolt 7 is threadedly connected to the inner wall of the adjustment frame 4. One end of the fixing bolt 7 is engaged with the surface of the slide rail 3, so that the adjustment frame 4 can be moved to a suitable position by means of the slide rail 3 and fixed by means of the fixing bolt 7. Several limiting grooves 8 are opened on the surface of the slide rail 3, so as to increase the friction between the fixing bolt 7 and the slide rail 3 by means of the limiting grooves 8.

[0027] Alternatively, a shield 9 can be installed on the surface of the machine body 1. An adjusting plate 10 is slidably connected to the inner wall of the shield 9, so as to shield the perimeter of the fixing frame 2 with the shield 9 and the adjusting plate 10, avoiding injury to the monitor 6 or surrounding personnel caused by the breakage of the detection material. The inner walls of both the shield 9 and the adjusting plate 10 are provided with slots 11, and the inner walls of the slots 11 are engaged with limit blocks 12. The surface of the limit block 12 is rotatably connected to the inner wall of the adjusting plate 10, and a fixing spring 13 is installed between the limit block 12 and the adjusting plate 10, so as to push the limit block 12 with the fixing spring 13, thereby engaging the limit block 12 with the inner wall of the slot 11, facilitating the upward movement of the adjusting plate 10 with the help of the limit block 11. 2. Fix the limiting block 12 and the slot 11 to facilitate the retraction of the adjusting plate 10. A connecting frame 14 is installed at the bottom of the shield plate 9. The bottom of the connecting frame 14 is slidably connected to the slider 15 on the surface of the machine body 1, so that the shield plate 9 can be easily installed on the surface of the machine body 1 with the help of the connecting frame 14 and the slider 15. Separating the connecting frame 14 and the slider 15 facilitates the disassembly of the shield plate 9. The inner wall of the connecting frame 14 is rotatably connected to the limiting frame 16. A connecting spring 17 is installed between the limiting frame 16 and the connecting frame 14, so that the limiting frame 16 can be pushed with the help of the connecting spring 17 to keep the limiting frame 16 locked to the surface of the slider 15, effectively improving the stability of the shield plate 9.
